"Get visitors real time" fails after upgrade 2.10

All worked fine, only the widget “visitors in real time” fails. I already deactivated the plugin and activated it again and cleared all tmp files. No change.

Error message:
Key “plugins” for array with keys “idSite, idVisit, visitIp, visitorId, actionDetails, goalConversions, siteCurrency, siteCurrencySymbol, serverDate, visitServerHour, lastActionTimestamp, lastActionDateTime, userId, visitorType, visitorTypeIcon, visitConverted, visitConvertedIcon, visitCount, firstActionTimestamp, visitEcommerceStatus, visitEcommerceStatusIcon, daysSinceFirstVisit, daysSinceLastEcommerceOrder, visitDuration, visitDurationPretty, searches, actions, referrerType, referrerTypeName, referrerName, referrerKeyword, referrerKeywordPosition, referrerUrl, referrerSearchEngineUrl, referrerSearchEngineIcon, deviceType, operatingSystem, operatingSystemCode, operatingSystemIcon, browserFamily, browserFamilyDescription, browser, browserName, browserIcon, browserCode, browserVersion, events, continent, continentCode, country, countryCode, countryFlag, region, regionCode, city, location, latitude, longitude, visitLocalTime, visitLocalHour, daysSinceLastVisit, provider, providerName, providerUrl, customVariables, serverTimestamp, serverTimePretty, serverDatePretty, serverDatePrettyFirstAction, serverTimePrettyFirstAction” does not exist in “@Live/getLastVisitsStart.twig” at line 12

I got rid of the error after (re?)activating DevicePlugins. According other reports Resolution and DevicePlugins must be activated.

Thanks for the report! we will fix it in Key "plugins" for array with keys does not exist in "@Live/getLastVisitsStart.twig" at line 12 · Issue #6979 · matomo-org/piwik · GitHub
